The BriteNway windshield is perfect for these hot summer days. It will protect your car from direct sun and heat, you will not have to open all your windows to cool down the inside of your car before getting in. You can put the windshield inside of the car or on the outside of the window, both ways it will work equally effectively. The windshield can also be used in winter, if you leave your vehicle on the driveway and in the morning your windscreen is all frozen, it can take an age to defrost when you are late for work. Using the windshield will prevent the windows from freezing through the night and in the morning you simply remove the shield in seconds and drive away.The BriteNway product comes with a small pouch for optimum storage that will fit in the pockets of the doors or be easy to throw in the boot. One side of the windshield is silver and other is black. To protect your car from heat, point the silver side to the sun. Good product.
